Policy Quality Degradation and Cross-Institution Blind Spots When New Policy Versions Are Drafted From LLM Interpretations of Prior Versions

Research Question

What policy-quality degradation and systemic blind-spot risks emerge when organisations draft new policy versions from Large Language Model (LLM) interpretations of previous policy versions?

Scope

In scope:

Estimate degradation rates in policy clarity and consistency when drafting loops repeatedly pass through AI interpretation layers
Assess whether common dependence on similar foundation-model families, meaning shared general-purpose base models, can produce cross-institution compliance blind spots
Define monitoring signals for repeated AI-mediated policy homogenization risk before failures materialize

Out of scope:

Implementing production policy-assistant software
Entity-specific legal advice
Exhaustive jurisdiction-by-jurisdiction legal analysis

Constraints: Use publicly available sources, distinguish demonstrated evidence from inference, and prioritise sources with explicit governance or empirical grounding.

Context

Workflow context: isolated from the broader multi-question issue for standalone investigation.

Approach

§2 Investigation

Source-characterisation notes

[fact] The regulatory and standards documents in this item are primary sources for obligations and systemic-risk framing, but they are normative rather than incident datasets, so they describe required controls better than observed failure frequency. [source: https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng; https://www.nist.gov/itl/ai-risk-management-framework; https://airc.nist.gov/AI_RMF_Knowledge_Base/Playbook; https://www.bis.org/publ/arpdf/ar2024e3.htm; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/]
[fact] The arXiv studies in this item are primary sources for their experiments, but none is a field study of repeated policy drafting inside organisations, so transfer to policy documents requires inference. [source: https://doi.org/10.48550/arXiv.2305.17493; https://doi.org/10.48550/arXiv.2311.16822; https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012; https://doi.org/10.48550/arXiv.2211.03540; https://doi.org/10.48550/arXiv.2509.08514; https://doi.org/10.48550/arXiv.2407.06798]

1. Degradation rates in repeated AI-mediated drafting

[fact] No consulted source reports a public, policy-document-specific percentage degradation rate for repeated drafting of policies from Large Language Model outputs. [source: https://doi.org/10.48550/arXiv.2305.17493; https://doi.org/10.48550/arXiv.2311.16822; https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012]
[fact] Shumailov et al. report that recursive use of model-generated content in training makes tails of the original content distribution disappear and produces irreversible defects, which they call model collapse. [source: https://doi.org/10.48550/arXiv.2305.17493]
[fact] Briesch et al. find that a self-consuming training loop for Large Language Models preserves correctness longer than diversity, and that fresh data slows the diversity decline without stopping it. [source: https://doi.org/10.48550/arXiv.2311.16822]
[fact] Ravaut et al. find that Large Language Model summarization exhibits a U-shaped position bias that favors early and late content, creating omission risk when important information is dispersed across a long text. [source: https://doi.org/10.48550/arXiv.2310.10570]
[fact] Wang et al. find that iterative retrieval and rewriting can progressively lose critical facts in generation, describing this as a lost-in-the-middle phenomenon for multi-fact tasks. [source: https://doi.org/10.48550/arXiv.2410.21012]
[inference] Applied to policy drafting, repeated AI reinterpretation is therefore more likely to compress rare clauses, exceptions, and edge conditions than to preserve them neutrally. [source: https://doi.org/10.48550/arXiv.2305.17493; https://doi.org/10.48550/arXiv.2311.16822; https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012]

2. Human review and automation bias

[fact] Beck et al. conducted a randomized experiment with 2,784 participants and found that reviewer attitudes toward AI and workflow design strongly affected accuracy, with required correction work increasing acceptance of incorrect AI suggestions. [source: https://doi.org/10.48550/arXiv.2509.08514]
[fact] Bowman et al. show that humans using an unreliable Large Language Model assistant can outperform both the model alone and unaided humans on difficult question-answering tasks, which means human-AI review can help when the workflow encourages substantive checking. [source: https://doi.org/10.48550/arXiv.2211.03540]
[fact] Harašta et al. find that lawyers and law students preferred legal documents they believed were human-crafted, even while expecting automated document generation to become common. [source: https://doi.org/10.48550/arXiv.2407.06798]
[fact] Article 14 of the European Union Artificial Intelligence Act requires deployers of high-risk AI systems to enable humans to understand limits, detect anomalies, interpret outputs correctly, and remain aware of automation bias, meaning over-reliance on automated output. [source: https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng]
[inference] Human review is a conditional control rather than a guaranteed safeguard, because performance depends on reviewer skepticism, workload, and real authority to challenge outputs. [source: https://doi.org/10.48550/arXiv.2509.08514; https://doi.org/10.48550/arXiv.2211.03540; https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng; https://github.com/davidamitchell/Research/blob/main/Research/completed/2026-02-28-ai-line-1-line-2-risk-agents.md]

3. Shared-model dependence and systemic blind spots

[fact] The Bank for International Settlements states that widespread Artificial Intelligence adoption affects financial stability and that central banks face trade-offs in using external versus internal AI models and data. [source: https://www.bis.org/publ/arpdf/ar2024e3.htm]
[fact] The Financial Stability Board identifies third-party dependencies, service-provider concentration, market correlations, cyber risks, and model risk, data quality, and governance as AI-related vulnerabilities with systemic-risk potential in finance. [source: https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/]
[fact] The prior completed Reserve Bank of New Zealand supervisory-expectations item found that New Zealand supervisory commentary aligns with the concentration-risk framing used by international financial authorities. [source: https://github.com/davidamitchell/Research/blob/main/Research/completed/2026-02-28-rbnz-ai-supervisory-expectations.md]
[inference] If many organisations use the same foundation models, vendor policy assistants, or prompt libraries to rewrite internal rules, then blind spots can align across institutions because the same omissions and interpretive shortcuts recur. [source: https://www.bis.org/publ/arpdf/ar2024e3.htm; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/; https://doi.org/10.48550/arXiv.2305.17493; https://doi.org/10.48550/arXiv.2311.16822]

4. Monitoring signals

[fact] Article 9 of the European Union Artificial Intelligence Act requires a continuous iterative risk management system that is updated throughout the lifecycle of a high-risk AI system. [source: https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng]
[fact] The National Institute of Standards and Technology AI Risk Management Framework and Playbook organise risk work around Govern, Map, Measure, and Manage, and describe the Playbook as a living resource that should evolve as AI technology advances. [source: https://www.nist.gov/itl/ai-risk-management-framework; https://airc.nist.gov/AI_RMF_Knowledge_Base/Playbook]
[inference] A useful monitoring set for repeated policy-drafting risk includes rising textual similarity across successive versions, shrinking numbers of fresh external citations, repeated omission of exception clauses, high reviewer acceptance with minimal edits, and concentration of drafting activity on one vendor or one model family. [source: https://www.nist.gov/itl/ai-risk-management-framework; https://airc.nist.gov/AI_RMF_Knowledge_Base/Playbook; https://doi.org/10.48550/arXiv.2509.08514; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/]
[inference] A policy loop should be treated as unstable when those signals move together, because that pattern combines fidelity loss, over-reliance, and concentration risk rather than a single isolated failure mode. [source: https://doi.org/10.48550/arXiv.2311.16822; https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2509.08514; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/]

§3 Reasoning

[fact] The evidence directly establishes three mechanisms that matter for this item: diversity loss under recursive generation, omission bias in long-context summarization or rewriting, and reviewer over-reliance shaped by workflow design. [source: https://doi.org/10.48550/arXiv.2305.17493; https://doi.org/10.48550/arXiv.2311.16822; https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012; https://doi.org/10.48550/arXiv.2509.08514]
[inference] The step from those mechanisms to policy-quality degradation is warranted because policies are long, exception-heavy texts where omitted edge cases and shared phrasing change real obligations. [source: https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012; https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng]
[assumption] Internal policy documents behave like other long-form, multi-fact texts for the purposes of omission and compression risk, because no public benchmark in the consulted evidence isolates this exact workflow. [source: https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012]
[inference] The absence of a policy-specific degradation rate lowers confidence in the numeric part of the research question but does not erase the direction of risk. [source: https://doi.org/10.48550/arXiv.2305.17493; https://doi.org/10.48550/arXiv.2311.16822]

§4 Consistency Check

[fact] No consulted source contradicts the claim that shared-provider concentration is a systemic AI risk, because both the Bank for International Settlements and the Financial Stability Board name concentration or correlated behaviour explicitly. [source: https://www.bis.org/publ/arpdf/ar2024e3.htm; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/]
[fact] The main tension in the evidence is that human-AI collaboration can improve outcomes in some tasks while still failing under poor workflow design or over-trusting reviewers. [source: https://doi.org/10.48550/arXiv.2211.03540; https://doi.org/10.48550/arXiv.2509.08514]
[inference] The item resolves that tension by treating human review as effective only when review is substantive, skeptical, and operationally empowered. [source: https://doi.org/10.48550/arXiv.2211.03540; https://doi.org/10.48550/arXiv.2509.08514; https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng]
[inference] Overall confidence remains medium because the mechanisms are strongly evidenced but the exact policy-document loop is inferred rather than directly measured. [source: https://doi.org/10.48550/arXiv.2305.17493; https://doi.org/10.48550/arXiv.2311.16822; https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012]

§5 Depth and Breadth Expansion

Technical lens

[fact] The strongest direct technical risks are diversity collapse under recursion and omission of dispersed detail during long-context summarization or iterative rewriting. [source: https://doi.org/10.48550/arXiv.2305.17493; https://doi.org/10.48550/arXiv.2311.16822; https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012]

Regulatory lens

[fact] The European Union Artificial Intelligence Act, the National Institute of Standards and Technology AI Risk Management Framework, and prior assurance research all converge on lifecycle risk management, documentation, anomaly detection, and empowered human override as the relevant control pattern. [source: https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng; https://www.nist.gov/itl/ai-risk-management-framework; https://airc.nist.gov/AI_RMF_Knowledge_Base/Playbook; https://github.com/davidamitchell/Research/blob/main/Research/completed/2026-02-28-ai-control-testing-and-assurance.md]

Economic and systemic lens

[fact] Shared-model dependence matters at the system level because official financial-stability sources identify concentration and correlated behaviour as vulnerabilities that can amplify shocks beyond one institution. [source: https://www.bis.org/publ/arpdf/ar2024e3.htm; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/]
[inference] The same concentration logic applies to policy drafting tools, even though the immediate output is text rather than a trading or credit decision, because policies shape downstream operational and compliance choices. [source: https://www.bis.org/publ/arpdf/ar2024e3.htm; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/; https://github.com/davidamitchell/Research/blob/main/Research/completed/2026-02-28-rbnz-ai-supervisory-expectations.md]

Behavioural lens

[fact] Reviewer psychology matters because experimental evidence shows both over-reliance and under-trust can distort the quality of human-AI collaboration. [source: https://doi.org/10.48550/arXiv.2509.08514; https://doi.org/10.48550/arXiv.2407.06798]
[inference] For policy workflows, this means governance must focus not only on model quality but also on review design, reviewer mix, and escalation authority. [source: https://doi.org/10.48550/arXiv.2509.08514; https://doi.org/10.48550/arXiv.2211.03540; https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng]

§6 Synthesis

Executive summary:

Repeated drafting of policy versions from Large Language Model interpretations of earlier versions is likely to degrade policy fidelity and align blind spots across organisations that depend on the same model families, prompt libraries, and review habits, even though no public study yet quantifies a policy-specific degradation rate. [inference; source: https://doi.org/10.48550/arXiv.2305.17493; https://doi.org/10.48550/arXiv.2311.16822; https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012; https://www.bis.org/publ/arpdf/ar2024e3.htm; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/] The strongest direct evidence comes from adjacent literatures: recursive self-consumption reduces diversity, long-context summarization and iterative retrieval lose dispersed facts, and reviewer performance degrades when workflows encourage over-reliance on AI suggestions. [fact; source: https://doi.org/10.48550/arXiv.2311.16822; https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012; https://doi.org/10.48550/arXiv.2509.08514] Some policy convergence would occur even without shared models because organisations respond to the same legal, prudential, and standards requirements, but shared tools can further narrow which interpretations survive drafting and review. [inference; source: https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng; https://www.nist.gov/itl/ai-risk-management-framework; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/] Existing governance frameworks do not specify policy-drafting-loop controls directly, but they support the same inferred control pattern, namely continuous risk management, monitoring, documentation, human override, and explicit treatment of automation bias and provider concentration as material risks. [inference; source: https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng; https://www.nist.gov/itl/ai-risk-management-framework; https://airc.nist.gov/AI_RMF_Knowledge_Base/Playbook; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/]

Key findings:

[inference] Public evidence does not support a policy-specific numeric degradation rate, but it does show that repeated model-mediated rewriting and self-consuming loops reduce diversity and drop less salient information, so repeated policy redrafting should be treated as a compounding fidelity-loss process rather than a neutral translation step. (Medium confidence; source: https://doi.org/10.48550/arXiv.2305.17493; https://doi.org/10.48550/arXiv.2311.16822; https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012)
[inference] Long policy texts are especially exposed because Large Language Model summarization and iterative retrieval studies show positional and lost-in-the-middle failures, which means exceptions, edge cases, and middle sections are more likely to be dropped than headline principles during repeated drafting loops. (Medium confidence; source: https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012)
[inference] Some policy convergence would happen even without shared models because organisations respond to common legal and prudential requirements, but shared foundation-model providers or policy-assistant vendors can add systemic blind-spot risk by narrowing which interpretations and omissions recur across institutions. (Medium confidence; source: https://www.bis.org/publ/arpdf/ar2024e3.htm; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/; https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng; https://github.com/davidamitchell/Research/blob/main/Research/completed/2026-02-28-rbnz-ai-supervisory-expectations.md)
[inference] Human review can improve outcomes but is not a failsafe, because experiments show both that human-AI collaboration can outperform humans or models alone and that poorly designed review workflows can increase acceptance of incorrect Artificial Intelligence suggestions. (High confidence; source: https://doi.org/10.48550/arXiv.2211.03540; https://doi.org/10.48550/arXiv.2509.08514; https://github.com/davidamitchell/Research/blob/main/Research/completed/2026-02-28-ai-line-1-line-2-risk-agents.md)
[inference] Governance frameworks do not specify policy-drafting-loop controls directly, but they support the same inferred control pattern: continuous lifecycle risk management, anomaly detection, documentation, empowered human override, and explicit guardrails against automation bias. (Medium confidence; source: https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng; https://www.nist.gov/itl/ai-risk-management-framework; https://airc.nist.gov/AI_RMF_Knowledge_Base/Playbook; https://github.com/davidamitchell/Research/blob/main/Research/completed/2026-02-28-ai-control-testing-and-assurance.md)
[inference] A candidate early-warning set for repeated policy-drafting homogenization includes rising similarity between versions, declining use of fresh external sources, repeated omission of exception clauses, minimal reviewer edits, and concentration of drafting on one model family or vendor stack. (Low confidence; source: https://www.nist.gov/itl/ai-risk-management-framework; https://airc.nist.gov/AI_RMF_Knowledge_Base/Playbook; https://doi.org/10.48550/arXiv.2509.08514; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/)

Assumptions:

[assumption] Internal policy documents behave like other long-form, multi-fact texts for omission and compression risk. Justification: no public benchmark in the consulted evidence isolates repeated policy drafting itself. [source: https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012]
[assumption] Organisations that reuse the same drafting tool often reuse similar prompt templates, review norms, and vendor defaults. Justification: the systemic-risk case depends on shared operating patterns, not only shared model weights. [source: https://www.bis.org/publ/arpdf/ar2024e3.htm; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/]

Analysis:

The strongest evidence in this item is mechanistic rather than field-measurement evidence, because the consulted studies measure recursive generation, summarization, iterative retrieval, and human-review behavior rather than an enterprise policy-versioning corpus.

§7 Recursive Review

Review result: pass.
Acronym audit: first-use expansions checked for Artificial Intelligence (AI), Large Language Model (LLM), National Institute of Standards and Technology (NIST), Artificial Intelligence Risk Management Framework (AI RMF), Bank for International Settlements (BIS), and Financial Stability Board (FSB).
Domain-term audit: automation bias defined as over-reliance on automated output at first use; model collapse, lost-in-the-middle, and foundation-model concentration anchored to cited sources at first use.
Claim audit: every visible claim in Research Skill Output labeled as fact, inference, or assumption, with URL-backed support where required.
Cross-item integration: prior completed items on RBNZ expectations, line 1 and line 2 risk agents, and AI control testing cited where they sharpened governance conclusions.
Confidence result: medium, because the core mechanisms are well evidenced but policy-specific degradation rates remain unmeasured in the consulted evidence.

Findings

Executive Summary

Repeated drafting of policy versions from Large Language Model interpretations of earlier versions is likely to degrade policy fidelity and align blind spots across organisations that depend on the same model families, prompt libraries, and review habits, even though no public study yet quantifies a policy-specific degradation rate. [inference; source: https://doi.org/10.48550/arXiv.2305.17493; https://doi.org/10.48550/arXiv.2311.16822; https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012; https://www.bis.org/publ/arpdf/ar2024e3.htm; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/] The strongest direct evidence comes from adjacent literatures rather than enterprise policy corpora: recursive self-consumption reduces diversity, long-context summarization and iterative retrieval lose dispersed facts, and reviewer performance degrades when workflows encourage over-reliance on AI suggestions. [fact; source: https://doi.org/10.48550/arXiv.2311.16822; https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012; https://doi.org/10.48550/arXiv.2509.08514] Some policy convergence would happen even without shared models because organisations respond to the same legal, prudential, and standards requirements, but shared tooling can further narrow which interpretations survive drafting and review. [inference; source: https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng; https://www.nist.gov/itl/ai-risk-management-framework; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/] Shared-model dependence still turns a local drafting weakness into a wider governance risk because official financial-stability sources identify provider concentration and correlated behaviour as core Artificial Intelligence vulnerabilities, while the sibling authority-drift item shows how repeated interpretation already degrades verification inside one organisation. [inference; source: https://www.bis.org/publ/arpdf/ar2024e3.htm; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/; https://github.com/davidamitchell/Research/blob/main/Research/completed/2026-02-28-rbnz-ai-supervisory-expectations.md; https://github.com/davidamitchell/Research/blob/main/Research/completed/2026-05-17-ai-policy-ambiguity-authority-drift-policy-decay-risk.md] The practical response is to govern policy-drafting loops as lifecycle risk systems, with anomaly checks, reviewer challenge authority, and monitoring for both fidelity loss and provider concentration. [inference; source: https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng; https://www.nist.gov/itl/ai-risk-management-framework; https://airc.nist.gov/AI_RMF_Knowledge_Base/Playbook; https://doi.org/10.48550/arXiv.2509.08514]

Key Findings

Public evidence does not support a policy-specific numeric degradation rate, but it does show that repeated model-mediated rewriting and self-consuming loops reduce diversity and drop less salient information, so repeated policy redrafting should be treated as a compounding fidelity-loss process rather than a neutral translation step. ([inference]; medium confidence; source: https://doi.org/10.48550/arXiv.2305.17493; https://doi.org/10.48550/arXiv.2311.16822; https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012)
Long policy texts are especially exposed because Large Language Model summarization and iterative retrieval studies show positional and lost-in-the-middle failures, which means exceptions, edge cases, and middle sections are more likely to be dropped than headline principles during repeated drafting loops. ([inference]; medium confidence; source: https://doi.org/10.48550/arXiv.2310.10570; https://doi.org/10.48550/arXiv.2410.21012)
Some policy convergence would happen even without shared models because organisations respond to common legal and prudential requirements, but shared foundation-model providers or policy-assistant vendors can add blind-spot risk by narrowing which interpretations and omissions recur across institutions. ([inference]; medium confidence; source: https://www.bis.org/publ/arpdf/ar2024e3.htm; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/; https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng; https://github.com/davidamitchell/Research/blob/main/Research/completed/2026-02-28-rbnz-ai-supervisory-expectations.md)
Human review can improve outcomes but is not a failsafe, because experiments show both that human-AI collaboration can outperform humans or models alone and that poorly designed review workflows can increase acceptance of incorrect Artificial Intelligence suggestions. ([inference]; high confidence; source: https://doi.org/10.48550/arXiv.2211.03540; https://doi.org/10.48550/arXiv.2509.08514; https://github.com/davidamitchell/Research/blob/main/Research/completed/2026-02-28-ai-line-1-line-2-risk-agents.md)
Governance frameworks do not specify policy-drafting-loop controls directly, but they support the same inferred control pattern: continuous lifecycle risk management, anomaly detection, documentation, empowered human override, and explicit guardrails against automation bias. ([inference]; medium confidence; source: https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng; https://www.nist.gov/itl/ai-risk-management-framework; https://airc.nist.gov/AI_RMF_Knowledge_Base/Playbook; https://github.com/davidamitchell/Research/blob/main/Research/completed/2026-02-28-ai-control-testing-and-assurance.md)
A candidate early-warning set for repeated policy-drafting homogenization includes rising similarity between versions, declining use of fresh external sources, repeated omission of exception clauses, minimal reviewer edits, and concentration of drafting on one model family or vendor stack. ([inference]; low confidence; source: https://www.nist.gov/itl/ai-risk-management-framework; https://airc.nist.gov/AI_RMF_Knowledge_Base/Playbook; https://doi.org/10.48550/arXiv.2509.08514; https://www.fsb.org/2024/11/the-financial-stability-implications-of-artificial-intelligence/)
